The tank is overfilled. Only fill the gas tank to one inch below the top of the tank. Back pressure in the fuel line may be another cause, but that is remotely possible since it would require a very clogged air filter and defective intake valve (4 cycle engine).
panic !
First thing to check is the gas cap. Make sure that the small hole in the cap is clear. If the air can't get in the gas can't get out.
That depends on the model/make of lawnmower, but it will always be on top.
if its regular gas
no get new gas
Not really sure what you're getting at. If your lawnmower engine is a 2-stroke then you need a mixture of oil and gas to run it.
it depends... if you have a drive mower than you should have a hose that runs from your gas tank into a fuel filterer you unclip it the gas will leak out you can probly find it if you locate the gas tank just look for a tube,and if its a push lawnmower you should do the same,or you can tip the lawnmower over with the gas lid off,and let the gas drain out into a pan or so.
Just gas. MOGAS, 87 Octane. There is reason they call it lawnmower gas. Intek OHV is just another lawnmower engine.
it is gas only no oil is added to the gas
to put the oil in the lawnmower's crankcase would be fine, so long as it is an appropriate viscosity.
If your lawnmower is a 2 stroke mixing oil in the gas is what it needs to run right. If your lawnmower is a 4 stroke mixing oil in the gas fouls the plug and makes it not run.
If your lawnmower stops working after five seconds of use, you may need gas. It can also be a problem with your fuse.
